    • Unexposed film in roll form is fed to an exposure station. At the station, a tray assembly for holding the fische original slides perpendicularly to the direction of travel of the film. The tray comprises a platen connected to a lower plate by pivot arms so that when the tray assembly is slid toward the exposure station, the platen section contacts a fixed stop in the station while the lower plate continues to move laterally a short distance thereby pivoting the arms and causing the platen to be pressed upward against the unexposed film during exposure. Developing uses high pressure anhydrous ammonia. A pressure pad, which is heated, is pressed onto the film surface. A Teflon coating and small holes insure even heat distribution and the holes also allow air to escape from the film surface.
    • 未曝光的卷状胶卷被送入曝光台。 在车站,用于保持拼贴原稿的托盘组件垂直于胶片的行进方向。 托盘包括通过枢转臂连接到下板的压盘,使得当托盘组件朝向曝光站滑动时,压板部分接触站中的固定止动件,同时下板继续横向移动短距离,从而枢转 并且使得压板在曝光期间被向上压靠在未曝光的胶片上。 开发使用高压无水氨。 被加热的压力垫被压在膜表面上。 特氟龙涂层和小孔确保均匀的热分布,孔也允许空气从膜表面逸出。
